Abstract: An uncured acoustic absorbing member for cavity sealing comprises a thermally inert carrier (8, 28) and a thermally expandable material (6, 26) applied to the carrier (8, 28). The carrier (8, 28) contains openings (3) which become covered when the thermally expandable material (6, 26) is expanded to seal the cavity. The thermally expandable material (6, 26) may be in the form of substantially discontinuous segments (25) having an area in the range of 0.25 to 400 mm 2 . The substantially discontinuous segments (25) provide a highly uniform expansion of the material when it is thermally expanded. The acoustic absorbing members are particularly useful for sealing automotive cavities to provide acoustical abatement and to prevent the entry of fluids into the cavity.

Abstract: Expandable polymer compositions are used to reinforce or provide various types of insulation to cavities in structural elements. The polymer compositions include at least two different segments, which may or may not be joined. At least one of the segments will expand before another segment when heated. The fixst-to- expand segment forms a physical barrier to the expansion of later-expanding segments, thereby restricting the expansion of the later-expanding segment in at least one direction. In this manner, the location of the expanded polymer within the cavity can be easily and inexpensively controlled.
